TO ALLVWHOM IT MA'Y CONCERN:

B e it known Vthat I, WARREN I. MILLER, ofthe city, county, and State ofNeW York, have invented a new and improved Mode of Attaching Handles 'to Saws; and I do herebydeclare that the following is a full and e-xact description thereof, reference being had to the accompanying drawings, and to `letters of reference marked thereon.-

'.Ihe nature of my invention consists in providing the handle with two circular collars, made ofv suitable i strips of metal, the two ends of which are bent out from the circle-so as to stand 'at parallel lines, 'and are connected by 'a pin. Said pins or rivets are for the purposel of engaging the saw. An eccentric., forming the segment of a` circle, is attached to the handle central ybetween the-two collars,`and is made to act against the end of the saw by revolving-the handle, thus pressing thepins firmly into the notches in the saw-plate, thereby renderingfthe. handle firmly )fixed 'to the saw. v

To enable others skilledvin the art to makeI and use my invention, I'will proceed to describe its construction and operation. A i v turn the handle round, of convenient shape and size, the lower end of which is-prvided with a shoulder to prevent the collars from falling oi. I make the collars of iron, one-eighth hy three-fourths inch, bend the strips of iron around al mandrel, turn the two'ends out at right angles from the ring, so that they stand at -parallel lines, and distant from eachother the thickness of a saw-plate. Punch or drill holes in the ends ofthe collars 'and insert rivets. The collars must be put onto the handles -befor4 the rivets-are secured. Cast leccentrics oi' malleable iron, the inner circle of which must be the same as that of the handle, and in length, half` the circumference, pierce the centre, place it central between thcltwo collars, land attach it with a screw. 'File notches in each edge of the saw-plate, .distant from vtheA end, so that when the pins in the ends of the collars are dropped into them, the thin end of the eccentric will have room to pass between the saw and the-handle. Turn the handle so asto force the eccentric, and it will become rigidly xed'to the saw. To remove the handle, turn vit in the oppositedirection.

Figure No.1 is a sidcviewot' the sa'w with the handle attached.

Figure 2 is a section of a handle andthe eccentric.

Like letters refer to like parts on the drawings. l

Letters aaa are the handle; ietters b Z1, the saw-plateg letters cie c, the'collars; letters d do?, the'riv'ets or pins; letters e c e, the ecccntri'cs.

Aoperating for the purposes as shown and described.

l Claim. What claim as my invention, and desire to securcby Letters Patent, is The collars c c, pins d, fitting in notches in, saw, and the ccccntrics e e, when constructed,'applied, and
